I took bk mami advise and tried SUNRAYSIA prune juice ~ very effective!Bought small bottle(200ml)at Park'n superstore at $9.40 and mixed a bit warm water('cause I never eat prune b4). Today I bought large bottle (1litre) at $41.60 again.No need to mix water as smell/taste acceptable. HEARD bk mami said there's pregnancy edition but couldn't find yet(not so sweet + more fibre). Will search over Jusco/Wing On asap...
